The Group created with a name that adds a wildcard asterisk (*) is not supported in the Domino Environment. The recommendation is that you use only these characters for the name:
letters A - Z
numbers 0 - 9
ampersand (&)
dash (-)
period (.)
underscore (_)
apostrophe (')
space

The functionality should allow the group to be created with a name that adds a wildcard asterisk (*).
In the Database ACL, you can enter hierarchical names with a wildcard character (*) in the ACL. You can use wildcards in the common name and organisational unit components..
As per product document, you can use the wildcard asterisk(*) only at the leftmost portion of the ACL entry.
